HENRY I. LURYE, OF NEIV YORK, N. Y., ASSIGNOR OF ONE-FOURTH TO NATHANIEL H. LEWIS, OF SAME PLACE.

COMBINED LEAK AND FIRE ALARM.

SPECIFICATION forming part of Letters Patent No. 613,636, dated November 1, 1898.

Application filed November 19, 1897. Serial No. 659,169- (No model.)

T0 at whom it may concern: v

Be it known that I, HENRY I. LURYE, a citizen of the United States,residing at New York, in the county and State of New York, have invented new and useful Improvements in a Combined Leak and Fire Alarm, of which the following is a specification.

By means of this invention it can be determined when a sprinkler is discharging as well in case of fire as in case of accidental leakage, and the locality of the trouble can. be readily ascertained, as set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a diagrammatic view of the alarm system. Fig. 2 is a detail side elevation of a sprinkler and circuit-closing mechanism, partly in section. Fig. 3 is an end elevation of Fig. 2. Fig. 4 is an inverted plan View of Fig. 2.

In Fig. 1 are shown an electric battery 1, an audible alarm or bell 2, and a visual alarm or annunciator 3. The alarms are placed, of course, in observable positions, as at the front of a building. A stand-pipe 5 supplies water to any number of sprinkler-pipes 6 7 3, according to the number of floors or stories in the building to be equipped. As the operation for all floors is alike, only one floor, with its pipe, as 8, and one sprinkler thereof, may be considered in this description.

The pipe 8 has sprinklers, one of which is shown at 33, below which is a pan or shallow dish 53. When the sprinkler discharges or leaks, the corresponding pan 53, receiving some of the water discharged, is filled and by its consequent increased weight and the inertia or flow of water into such pan closes the circuit in a manner presently explained. The current now flows from battery 1 at pole along conductors 61 and 61 and conductor 63 64 65 to binding-post 66 of annunciator or visual alarm 3, so that the annunciator is made to expose a number-as, for example, 1 -indicating that there is trouble on the corresponding fioor 1, having sprinkler-pipe 3. From annunciator 3 the current passes along conductor 67 68 to post 69 of the hell or audible alarm 2, causing the latter to sound. From the bell the current passes by post 70 and conductor 71 back to the battery at pole 72 to complete the circuit.

The arrangement of pans 53 is shown by the pan in Figs. 2, 3, and 4. The pans or receivers 53 are each of annular or ring form, so as toallow the flame to readily reach the sprinklers 33. Such pan extends from lever 41 39, fulcrumed at 40, to a collar or attachment 34, clasped or secured by screws or fastenings 35 about the pipe 8. The lever-arm 41 has a rod 56, with adjustable balanceweight 55 so set that the pan when empty rests with arm 41 in vertical position or barely touching stop-screw 42 on a bracket 36 33, carried by collar or clamp 34. hen the pan is filled or overbalanced, the lever is swung to cause its arm 43 to bring the spring 49 into touch with spring 51 and closing the circuit along conductor 63. The circuit-closer 49 51 being now in action-,the current flowing along conductor 63 will elfect action of the alarms 3 and 2, as already explained.

In case the sprinklers or one of them is put in action by fire the wire or conductor 63 in course of time might be destroyed by the fire and the sounding of bell 2 prematurely stopped. This contingency is avoided by the following arrangement, whereby the magnet when vitalized closes a second magnet-circuit:

In its ordinary operation the current, as already explained, enters the bell mechanism at post 69, Fig. 1, and passes along conductor 7 8 to the well-known buzzer or make-andbreak armature 11, carrying clapper 23 for sounding bell 2-, such current flowing intermittently from the armature 11 to the contact 15, conductor 73, electromagnet 9, and conductor, 74 out at post 70 and conductor 71 to battery-pole 7 2, as already explained. The electromagnet 9 when vitalized also attracts a second armature 10, carrying a part 25 of a circuit-closer 25 26. These parts 25 26 when engaged or hooked to one another will not disengage until freed by hand. If now the conductor 63 should get out of action for any cause, a short electric circuit will continue made as follows: from battery-pole 60 along conductor 76 to post 75, along conductor 74', circuit-closer 26 25, armature 10, conductors 77 and 78, armature or buzzer 11, contact 15,

conductor '73, magnet 9, and conductor 74: to post 70, whence the current returns by conductor 71 to battery-pole 72. This short circuit will keep on sounding bell 2 until the circuit-closer parts 26 25 are freed or unhooked, as by hand.

Of course the device can be modified in various ways. For example, in speaking of the pan 53 as annular it is manifest that it need not be exactly ring-shaped. In fact, the pan 53 shown is semi-annular, such pan having been found to interfere but slightly with the flame reaching the adjacent sprinkler 33.

The collar or fastening 34 is shown with two longitudinal ribs 36, between which the lever 39 41 is fulcrumed at 40. Such collar or clamp 34': also has the hanger 38, carrying the stop or screw 42, alreadynoticed,and transverse arms or carriers 38 and 48, Fig. 4, for carrying or readily attaching the wires or conductors 61 and 63. Of course the several parts are insulated as requiredas, for example, the contact-maker or circuit-closer 49, Fig. 2, extending from wire or conductor carrier 4L8,'is insulated from lever-arm 39 to prevent loss or diversion of the current. Likewise the collar 34: can be insulated from pipe 8. Such details are obvious. Likewise the circuit-closer 25 26, Fig. 1, might be made of various forms so long as the principle remains that when said closer is actuated or closed it looks or remains permanently cl0sed-that is to say, closed until purposely released or freed. The signal mechanism when started thus keeps permanently sounding alarm until attention is attracted. As the sprinkler 33 has its contact mechanism provided with leads 61 and 63, so other contact mechanisms, as at sprinkler 33", Fig. 1, can have leads (31 and 63 for establishing connection between conductors 61 and 64.

The pan 53 when filled closes a circuit; but manifestly a closed-circuit arrangement could be applied and the pan 53 when filled be made to sound the alarm by breaking circuit.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. A pipe or conduit provided with a sprinkler and with longitudinal ribs and a hanger and transverse arms or conductor-carriers, combined with a lever fulcrumed between the ribs, a stop for the"lever carried by the hanger, and a circuit-closer connected to the lever and to a conductor-carrier, said lever having a receiver or dish placed in proximity to the sprinkler substantially as described.

2. A pipe or conduit provided with a sprinkler and with longitudinal ribs and a hanger and transverse arms or conductor-carriers, combined with a lever f ulcrumed between the ribs, a stop for the lever carried by the hanger, and a circuit-closer connected to the lever and to a conductor-carrier, said leverhaving a receiver or dish in proximity to the sprinkler and an adjustable weight for holding the lever to the stop substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
